How to Change a Bathroom Sink

Upgrading your bathroom sink is a relatively simple plumbing project that can significantly improve the look and functionality of your bathroom. Here's a comprehensive guide to help you change your bathroom sink like a professional. ### Preparation

1. Gather Tools and Materials:

* Adjustable wrench * Basin wrench * New sink * New faucet (if necessary) * Plumber's putty * Silicone caulk * Utility knife

2. Turn Off Water Supply:

* Locate the water shutoff valves under the sink and turn them off completely. * Open the faucet to release any remaining water from the pipes. ### Disconnecting the Old Sink

1. Disconnect Water Supply Lines:

* Use an adjustable wrench to disconnect the hot and cold water supply lines from the old faucet. * Be cautious not to overtighten or damage the lines.

2. Remove Old Faucet:

* Use a basin wrench to loosen and remove the nuts that hold the faucet in place. * Gently lift the faucet out of the sink.

3. Detach Drain:

* Use a utility knife to cut the old drain pipe below the sink. * Clean any remaining putty or sealant from the drain hole. ### Installing the New Sink

1. Apply Plumber's Putty:

* Roll a rope of plumber's putty into a ring and place it around the drain hole in the new sink. * Smooth the putty over the flange of the drain hole to create a watertight seal.

2. Position and Seat the Sink:

* Carefully lift the new sink into place and align it with the drain hole. * Gently press down on the sink to seat it onto the plumber's putty.

3. Reconnect Water Supply Lines:

* Connect the new faucet to the water supply lines using the adjustable wrench. * Tighten the nuts securely, but avoid overtightening.

4. Install Drain:

* Apply a small amount of plumber's putty to the end of the new drain pipe. * Insert the pipe into the drain hole and tighten the locknut underneath the sink. ### Finishing Touches

1. Apply Silicone Caulk:

* Run a bead of silicone caulk around the edges where the sink meets the countertop or vanity. * Use a damp cloth to smooth the caulk and remove any excess.

2. Turn On Water Supply:

* Turn on the water shutoff valves and check for any leaks. * If there are any leaks, tighten the connections or apply additional caulk. ### Tips for a Successful Installation * Use a level to ensure the sink is level before tightening the drain. * Remove any excess caulk immediately to prevent it from hardening. * Allow the caulk to dry completely before using the sink. * If you encounter any difficulties, do not hesitate to consult a professional plumber.
